If you’re stuck on the ground in London due to the volcanic ash cloud, here’s some cheering news at last. Merlin Entertainments is offering stranded travellers half-price tickets to top London attractions including:

All you need to do is present your unused flight ticket (or e-ticket) and passport at the attraction’s ticket desk within two weeks of the flight being cancelled and you’ll only need to pay half the ticket price!

The offer ends on 14 May, but may be renewed if air traffic restrictions continue.
